Layers are glitching - masking errorsOpen for Voting

So I am running into the following issue when I am trying to create some textures for a personal project:  This glitch is happening on all layers and all channels, and there is only one texture set I am working with.  I have tried closing out the project and restarting, and I have also tried to remake this project, with the same results

3D blur filterIn Development

There is an issue with the blur filter that has been around since the first version of Substance Painter, and I can't understand why it hasn't been addressed yet. The issue happens when you try to blur something close to a UV seam - which is often unavoidable. Example: Note: while there is a workaround involving the blur tool to mitigate these artifacts, it demands a considerable amount of effort. Moreover, it's easy to miss these artifacts if we do not meticulously inspect the entire model.  Is there any plan to resolve this issue permanently? I have observed numerous colleagues expressing frustration over this. Please give this matter the attention it deserves.   Thanks.

How to fix Random Grey patches?

I get this Issue occassionally where substance painter just adds random grey patches when I bake models, I often fix it but I forget how to so I'm asking how.I've tried: exporting as an fbx and an obj filereunwrapping several times, with smart uv and regular unwrapremaking the faces that bug outmerging the model by distancetriple checking the uvs are not overlappingno other meshes are nearbyno uv islands are hiddenbelow is how the model looks in  Substance Painter vs BlenderHelp would be very appreciated!

Export the "Automatic" cage mesh?Under Review

Automatic cage mesh is an amazing feature but I noticed there's always a few buggy quirks in the cage generation that unfortuantely make it unusable.But if we could export out the cage mesh, then we could just make small manual adjustments.Somewhat related, anyone know where the cage mesh is stored? Was hoping for a workaround for now.

I want to paint on a UV map using the paint tool.When using the paint tool, how can I prevent the painted areas from invading adjacent UV maps?Is there a way to select areas like in illustration software?

Curvature maps generate inconsistently, leading to asymmetrical edge wear application.Open for Voting

Version: Substance 3D Painter 2025 - Whatever is live on Steam right now.Platform: PC, Windows 11Reproduce: Bake all maps for a symetrical angular hard surface model. Apply painted steel smart material. Observe that edge wear is applied asymmetrically, and that the curve map is generated assymmetrically.Expected result: Curvature map is generated symmetrically for the model regardless of UV island positions.Actual result: Curvature map has small differences despite being largely correct. I am encountering an issue where auto-baked curvature maps are generating inconsistently on a symmetrical model. This has resulted in the issue below, where edge wear is asymmetrically applied on the back of the model. Red is where it has applied, blue is where it has not.I believe this to be caused by the curvature map  baking improperly. This is the curvature map of the same area, and as can be seen from the texture dilation, one side has generated a lighter curvature line, while the other

Substance Painter Freezing when Launched on Second Monitor

Hi, I am having an issue where Substance Painter 3D will freeze when launching on my tablet (working as a second monitor as well). It gets stuck on a white screen that looks like the following: Then I must close Substance Painter, uninstall and reinstall, or disconnect and reconnect my tablet to get it working again. I'm beginning to get annoyed with the tedium. I am running on Windows 11 and using a XP-Pen Pro 22E tablet for the second monitor. I do not have this problem on my personal station that operates off of windows 10 and an older Cintiq 22 as the second monitor.I have tried updating every single driver and trying every older version of substance painter available. I am not sure what else is left to do. If there is a solution to this problem, I'd be happy to hear it!

Is there a soften/blur tool for hand painting?

I'd like to know if there's a similar tool, as I sometimes paint by hand and I honestly need something to smooth the edges between each paint stroke

preserve bitmap aspect, numerical fieldsOpen for Voting

1. Painter should be better at processing imported bitmaps - it should have an option to preserve original image proportions if they are not square.2. After undocking a window, its numerical fields sometimes do not work properly.

"Failed to Decode Bitmap" Error When Using UDIM Textures

Hi,I just got Substance Painter to paint UDIM models, but this infuriating glitch won't let me. Whenever I import a UDIM texture set, it gives me the "failed to decode bitmap" error (in screenshot below), then the entire texture set dissapears from the project panel when I reopen the project. I tried all the solutions previously listed on this forum. Renaming and reformatting the textures doesn't solve the issue. The only solution that does work right now for some reason is to delete the UDIM tile denotation in the texture's name (e.g. renaming "Diffuse_1001" to just "Diffuse"). But then that completely negates the UDIM import for those textures, making the solution redundant. I've been stuck trying to figure out a viable solution to this glitch for a week now and I'm starting to think of dropping this program. Can anyone please help resolve this? Thanks(P.S. here is the attached error log as well).

I have not used my Perpetual Painter and Designer for since before Substance accounts were closed

I need them back quickly for a project which can only be done a new PC, the GPU on the last PC it was on broke.Support page said that as long as both accounts use the same email, I can retrieve the license key. I want to use those specific versions (2020 versions) so a trial is no option for me due to no backwards compatibility.I found an official download of that version but is only asks for Substance account and licence file.I have the licence keys already via the original emails.

Lost my substance download points - how can I gain access to assets which I already paid for?

I had a longstanding subscription and gained lost of substance points. I occasioanlyl downladed stuff with them. Recently I realized my points and ability to get stuff was gone. This is highly upsetting for two reasons:1. I already paid for the points2. I can't afford a subscription to download stuff. And either way - I had SOOOOOO many points - now I would have to PAY for a LIMITED amount of points per months. What can be done?

Question: How to scale smart material to your mesh?

Hello! This may be a dumb question. But, when I put my smart material on my mesh, it is really scaled up, so it looks really ridiculous. For reference, I'm trying to make planks of wood, and when I made the material it was all great and was the correct scale. But, when I placed it on my object, it was all HUGE and only showed like 4 huge planks. Thank you all so much in advance - A substance painter noob
